LOOMQ SHUTTLE.

SPECIFICATION forming part of Letters Patent NO. 734,189, dated. July 21, 1903. Application filed March 30,1901; Serial illo- 63,6'73. (No mode To all whom it may concern Be it known that LPETER MORESLa citizen of the United States, and a resident of Paterson, in the county of Passaic and State of New Jersey, have invented a new and useful Loom- Shuttle, of which the following is a specificalion.

happened because of the difficulty the part of the operator to observeataglii nce whet-her one orboth of the threads were intact.

The object-0t my present invention is to provide a simple and effective means for causing the breakage of a companion thread when for any cause one 0f the threads-of the group being fed is broken, thus calling prompt attention to the fact of the breakage and preventing the weaving of one of the threadsindependently of its companion thread.

A practical embodiment ot myinvention is represented in the accompanying drawings,in which- Figure 1 is a top plan view of a two-quill shuttle, showing the parts in the position which they assume when the shuttle is in op eration. Fig. 2 is an enlarged top plan view of the central portion of the shuttle, showing the parts to which my invention particularly relates; and Fig. 3 view of the same in side elevation, the side of the shuttle being broken away to show the parts within it.

The shuttle is denoted by a and the wound quills by b and 0. These may be of any well-known or approved form in the present instance located within the shuttle with their tips over which the thread is withdrawn arranged toward each other and spaced apart. Within the space between the free ends of the quills band 0 there is fixed a frame,.in the present instance comprising a bottom plated, two upright end plates 6 and f, a cen- 'tral standard g, and rails 70 and 2', leading its dotted position.

from. the central standard g near its top to I the ends 9 andf and fixed in position. From the ends 6 and fguide-tubesj and 70 project in a slanting direction, as clearly shown inthe several figures, the slant being away from the central standard g. The central standard 9 has fixed thereto, in the present instance about midway of its height and preferably about the height of the guidetubesj and k, two pairs of eyes, the one pair being denoted by l m and the other pair by n 0. These pairs of eyes are located upon opposite sides of the central standard g, and themembers of each pair are in alinement and spaced apart to receive between them the eyes 1) and q, located at the juncture of the arms of L-shapcd stops suspended from the rails h and r'. The upright arms of these L shaped stops are provided with eyes rfand 5,,

The normal positions of the stops are indicated in full lines in the several figures'and they are thrown out of their normal positions only when their eyes 4' and s are permitted to slide up inclines o and w on the rails h and This happens only when they are freed from their position between pairs of eyes [wt and n o by the breaking of the thread and takes place at the moment the shuttle is abruptly stopped in' its box at the end of its throw, the momentum of the stop being sufficient to carry it from its normal position into (Shown in Fig. 3.)

The thread from the quill his denoted by w and that from the quill c is denoted by 1 The thread :2: passes into and through the guide-tube j, and from its free end. it passes through the eyes at o and also through the eye q in the stop which codperates with the quill c and thence extends up through the guide-ring z and out at the front of the shuttle.

goo

The thread y extends into and through the guide-tube k and from its free end through the eyes l'mand through the eye 19 in the stop which cooperates with the quill b and thence up through the guide-ring 2 and passes, together with the thread y, through the front of the shuttle.

When for 'any cause one of the threads breaks-as, for example, the thread y-it will immediately relievethestopwhich coacts with the quill b, carrying the thread to, permitting it to slide freely from between the eyes 1 and m, and this it will do when the shuttle is brought to a sudden stop at the end of its stroke, the eye r on the upright arm of the stop riding up the incline v into the dotted position shownin Fig. 3, presenting the horizontal arm t of the stop in proximity to or within the end of the quill 11, thereby causing the thread a; to wind around the arm t as it is withdrawn from the quill b and by so doing bind sufficiently to cause it to break. In the same manner it the thread as should break the stop which cooperates with the quill 0 would be free to jump forward under its own momentum when the shuttle is suddenly stopped in its (light in the opposite di'-' rection, causing the stop to slide into position with its horizontal arm, where it catches the thread 1 and causes it to break.

The above arrangement thus provides for causing the companion thread to break when for any reason one of the threads breaks, thus calling the operators attention to the defect and enabling him to correct it before serious damage is done.

able toward and away from each of the threadsupplying means, the said stops being under the control of the threads and actuated by the stopping of the shuttle at the end of a pick to cause a companion thread to break when one of the threads breaks.

3. A shuttle provided with independent quills for supplying separate threads, stops -movable toward and away from the ends of the quills and thread-guides arranged for placing the said movable stops under the control of the threads from the quills to be held normally away from the quills, the stop corresponding to each quill being under the con-' trol of the thread from the companion quill whereby the breaking of the thread from one of the quills will release the stop corresponding to the other quill to cause its thread to break, substantially as set forth.

4. A shuttle provided with independent quills, guides for cond noting the threads from the quills to a common outlet from the shuttle, stops suspended intermediate of the ends of the quills inposition to slide order their momentum toward the ends of the quills, the said stops being provided with eyes normally located in position to receive the threads therethrough as they extend from the quills to the exterior of thesh'uttle, the stop corresponding to one of the quills being in position to receive the thread leading from the opposite quill whereby the releasing of one of the stops by the breaking of a thread from one of the quills will permit the stop to as-' sume a position to cause the breaking of a thread on the quillto which it corresponds, substantially as set forth.

In testimony that I claim the foregoing as my invention I have signed. my name, in presence of two witnesses, this 27th day of March, 1901.

PETER MORESI.
